るデイスク押え装置。[Claims for Utility Model Registration] A turntable equipped with a disk-shaped recording medium having an opening in the center, and a disk-shaped plate portion facing the turntable with the disk-shaped recording medium interposed therebetween; It is composed of a disk holding member for holding the disk-shaped recording medium between the turntable, and a disk holding member for holding the disk-shaped recording medium on the outer circumferential side of the surface facing the turntable of the disk holding member.
Then, on the inner circumferential side, a plurality of annular magnet means for attracting the turntable are attached concentrically to the surface corresponding to the opening of the disk-shaped recording medium.
The disk holding device further comprises a member to be attracted to the turntable at a position corresponding to the annular magnet means.
